    Abstract: A pumping system 10 is provided for pumping fluid from a downhole well to the surface through a production tubing string well. A rotatable drive rod 18 extends from the surface to power the downhole pump, and includes a plurality of rod couplings. The downhole pump includes a pump stator 22 and a rotor 24 rotatable within the pump stator. A lifting member 36 provided at the upper end of the stator is engaged by a drive coupling 34 to retrieve the pump from the well. The lifting member has an internal shoulder 44 tapered radially inwardly and upwardly, such that a rod coupling engages the internal shoulder and passes through the lifting member as the rotor is pulled upward.
